在maven web项目中的index.jsp中的错误信息如下：
The superclass "javax.servlet.http.HttpServlet" was not found on the Java Build Path
从错误信息可以看出来，找不到该类，也就是说找不到相应jar包。
所以解决方法就是引用相应jar包即可。
前提：
需要设置Server Runtime，
Window -> Perferences -> Server -> Runtime Environments -> Add -> Apache Tomcat ... , 这样一步步做下去即可。
此问题解决方法：
工程右键 -> Build Path -> Configure Build Path -> Libraries -> Add Library -> Server Runtime -> 选择通过上面上面步骤添加的server即可， 最后点击Apply。
就可以看到jsp页面上的错误消失。
但是你还会发现，工程上有一个小红叉，解决如下：
首先查看Markers信息 (Window–>show veiw–>Markers)
错误信息是：
Project configuration is not up-to-date with pom.xml. Select: Maven->Update Project... from the project context menu or use Quick Fix.
按提示步骤做即可解决问题！（工程右键 -> Maven -> Update Project）
